The spear and shield are actually painted MegaBloks weapons-- I found a ton of something called "Plasma Dragon" packs on clearance for $1 and each one has a bunch of interesting weapons like those. They're in obnoxious colors like trans-blue and neon orange, but they come out pretty nice once re-painted.
The Marauder soldier helmet is inspired. That's a great way of thinking "outside the box".
